Re: Weighted Cindy
We sometimes do a 10 minute version of Cindy... call it Mindy!
I think if I was doing it with a weighted vest - for the first time - I would likely do it for 10 minutes. Weighted pull ups and push ups are hell on your forearms and grip... 20 minutes of that could be agony.
Then again - the instructions for Murph say, "if you've got a vest wear it."
